Peach tree named &#39;nj351&#39;

ABSTRACT

A new and distinct peach variety of  Prunus persica  named ‘NJ351’ is provided. This variety is distinguished from other peach varieties by its unique combination of nonshowy flowers, fruit that ripen in late-midseason, attractively blushed fruit with a bright golden-yellow ground color, freestone fruit with a juicy, nearly nonmelting texture and sweet, low acid flavor, firm fruit that retain their firmness well and trees with regular, heavy production of fruit.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree named ‘NJ351’. Our new tree resulted from crossing ‘NJ304’ as the seed parent with ‘J19-19-862144’ peach tree, as the pollen parent. The new variety differs from seed parent ‘NJ304’ (unpatented) in that the new variety has firm fruit with yellow flesh while the parent has soft fruit with white flesh. The new variety differs from pollen parent ‘J19-19-862144’ (unpatented) in that the new variety has fruit with a bright ground color and yellow flesh, while the parent has fruit with a slight green ground color and white flesh. The resulting tree was selected when growing in a cultivated area as the 34^(th) tree in the 40^(th) row of Block K in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJ351’ variety is distinguished from other peach varieties due to the following unique combination of characteristics:

Fruit with an attractive red skin color.

Fruit with a bright golden-yellow ground color.

Fruit with a sweet, low acid flavor.

Very firm fruit that retain their firmness well.

Regular and heavy production of fruit.

The variety was asexually reproduced at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. Asexual reproduction of this new variety by budding onto ‘Lovell’ rootstock (unpatented) shows that the foregoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJ351’. The original tree and progeny have been observed growing in a cultivated area in Cream Ridge, N.J. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (such as, light, temperature, moisture, nutrient availability) or other factors. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (RHS) Colour Chart.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a color photograph taken on Aug. 29, 2005 of a characteristic twig of ‘NJ351’ in late summer bearing typical leaves of the mature foliage.

FIG. 2 is a color photograph of mature fruit of ‘NJ351’ and stones harvested in Cream Ridge, N.J. on Aug. 29, 2005. Whole fruit are presented in two positions and transverse and longitudinal cross sections to show that the pericarp comes free from the pit when the fruit is mature. The stones illustrate the medium, narrow dorsal ridge on the stone and the chains of pits forming grooves on the surface of the stone.

FIG. 3 is a color photograph of a characteristic twig that illustrates the typical flower buds and small non showy flowers of ‘NJ351’ observed on a tree in Cream Ridge, N.J. on Apr. 21, 2004.

FIG. 4 is a color photograph of a tree of ‘NJ351’ in early fall that illustrates the spreading growth habit of a tree in Cream Ridge, N.J. on Oct. 27, 2005.

FIG. 5 is a color photograph taken on Oct. 27, 2005 of immature bark of ‘NJ351’ that illustrates color and the moderate density of elongated lenticels on the immature bark.

FIG. 6 is a color photograph taken on Oct. 27, 2005 of mature bark of ‘NJ351’ that illustrates the fairly smooth texture and prominent lenticels of the mature bark.

The colors of and illustration of this type may vary with lighting and other conditions under which conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
